Record the actual review issue
The CSV contains fields for pairing, units, proxy identity, residual pattern, observation sensitivity and model/inference status. Blank evidence fields are intentionally unresolved; recording an item is not proof that the underlying assumption is valid.
Retain both estimation versions
The original full fit has slope 2.1/intercept 1.2%; leaving out its last pair gives 1.8/0.9%. Keep both sample identities and the reason for any proposed change rather than treating a smaller squared residual sum as automatic improvement.
Use plots as evidence for questions
| Issue | Next evidence |
|---|---|
| Curved residual pattern | Review functional form |
| Uneven spread | Review error-model assumptions |
| High leverage | Check source and influence context |
| Period mismatch | Resolve matching keys |
| Inference request | Specify sampling/error assumptions and method |
Avoid unsupported deletion or certification
The record does not automatically remove observations, certify normal residuals or recommend an investment. Retain the specific source error or model requirement before changing a data set.
